Although not the exact circuit that you are searching for, there is a lot of ARC information here:

(down the first page, click on Preamplifiers... follow the links to the circuits...)

I've heard plenty of ARC gear over the years, and while it sounds good, it is needlessly complex and actually doesn't sound better than (in many instances not even as good as) a lot of the designs floating around on this forum.

For a really good line stage you can build check out the Aikido threads here and http://www.tubecad.com/

If you want to build something a little different take a look at my dht pre-amplifier design. (See my site)

Kevin,

Thanks for the pointer towards your line stage. While I am not in the position to take on another project right at this moment I will certainly be returning to your site in the future for further inspiration.

Good luck.

Thanks Gordy,

I've built the LS25 schematic, and it is no way sounding anything near like a Reference 3!

I love the sound of the Ref 3 but thinking the LS25 is close enough, but it just will not do!

I've being tweaking on the LS 25 trying to make it sound more Ref 3 like but with limited sucess.

Does anyone here has the schematics to Ref 3 pre amp?

Please....?

If not on the ARC website, unlikely that you'll see it here anytime soon. ARC is less willing to share the designs of its (more) current products for very obvious reasons.
